The pharmaceutical industry faces challenges in developing efficient and cost-effective drug delivery systems. Among various applications, antibody-drug conjugates (ADCs) stand out by combining cytotoxic or bioactive agents with monoclonal antibodies (mAbs) for targeted therapies. However, bioconjugation methods can produce different outcomes, including no bioconjugation, depending on the mAb, amino acid residues, linker-payload (LP) system used. In this work, we developed a machine learning...

Abstract Background Alkaptonuria (AKU) is an ultra-rare autosomal recessive disease caused by a mutation in the homogentisate 1,2-dioxygenase (HGD) gene. One of main obstacles studying AKU, and other diseases, lack standardized methodology to assess severity or response treatment. Quality Life scores (QoL) are reliable way monitor patients’ clinical condition health status. QoL allow evolution diseases suitability treatments taking into account symptoms, general status care satisfaction....

The enzyme 4-hydroxyphenylpyruvate dioxygenase (4-HPPD) is involved in the catabolism of amino acid tyrosine organisms such as bacteria, plants, and animals. It catalyzes conversion to a homogenisate presence molecular oxygen Fe(II) cofactor. This represents key step biosynthesis important compounds, its activity deficiency leads severe, rare autosomal recessive disorders, like tyrosinemia type III hawkinsinuria, for which no cure currently available. 4-HPPD C-terminal tail plays crucial...
